One day after Donald J. Trump was inaugurated as the 45th President of the United States, women and men around the world are marching on cities around the world to protest the new Commander-in-Chief and promote women’s rights.

The Women’s March, as it’s called, originally centered on Washington, D.C. But the cause has spread quickly, and many other cities—New York, Los Angeles, Chicago, Boston, Denver, Houston, London, Paris, and so on—are experiencing turnout measured in thousands or tens of thousands.
